摘　　要：利用多模压缩态理论,对强度相等的两态叠加多模量子纠缠态(2MQES)光场|ψME(2)〉q的广义非线性高次Y压缩效应进行了仔细研究。发现在满足一定的条件下,2MQES光场|ψME(2)〉q的广义电场分量和广义磁场分量可分别呈现出广义非线性等幂次奇次Y压缩效应,且压缩规律相似,而磁场分量的压缩幅度和压缩量较大;同时指出导致2MQES光场|ψME(2)〉q的广义电场分量和广义磁场分量存在广义非线性等幂奇次Y压缩的根原在于模间的量子干涉效应、态间的量子干涉效应以及模间和态间的量子纠缠效应。The multimode squeezed state theory is used to the system researching the effect of the generalized nonlinear high-power Y-squeezing on the Equal-intensity of Two State-suporposition multimode quan- tum entanglement state（2MQES）light-field ｜ψME^（2〉q in detail. And the effect shows that the generalized non- linear equal-power odd-power Y-squeezing of the generalized electric-field component and the generalized mag- netic-field component of state ｜ψME^（2〉q can present under the certain condition is further revealed, even squeezed law is similar and both the squeezed amplitude and the squeezed quantity of the generalized magnet- ic-field component of the quantum light field are bigger than the generalized electric-field component. Finally it is pointed out that both the quantum interference effect and the quantum entanglement property of multimode light-field are the innate character that can cause the effect of equal-power odd-power Y-squeezing the general- ized electric-field component and the generalized magnetic-field component of state ｜ψME^（2〉q.
